Fuel Systems – Direct Injection
The configuration of any GDI system will vary according to age and application.
Curing Intermittent And Chronic Fuel Pump Failures
The fuel pump may be one of the most misdiagnosed components on a vehicle.
High-Pressure GDI Fuel Pumps
When solving a fuel pump issue, the scan tool is your best friend.
Gasoline Direct Injection: Total System Diagnostics
Modern gasoline direct injection (GDI) engines have two fuel pump opportunities. You still have an electric pump in the tank, but a high-pressure fuel pump is on the engine. These two pumps work in unison, so the correct quantity of fuel is injected directly into the cylinder. If either pump can’t generate the pressure or
EGR, Secondary Air Injection And Emissions Management
EGR systems put a small amount of inert gas into the combustion chamber to control the temperatures.
Gasoline Direct Injection Is Better, But Not Perfect
GDI technology has improved but drivers could face problems if they don’t keep up with maintenance.
Fuel Pressure Diagnostic Service
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.
